That is the reason it is called cycle, it just repeat what happens and nothing will change, some will go out of that chain but there will still be a lot of people that will be scammed and people will scam.
As long as there are a lot of people wanting and desperate to earn money, I don't think that it will be that easy to stop people being scammed. They will be feeding to it, they will be taking advantage of those desperation of people to earn and as long as people want to earn money the hard way, there will be always people that will want to earn the easy way.
